For a given​ piecewise-defined function, the pieces of the function are defined for intervals of the​ domain, x≤−1 and x>−1.

Explain how you could find the​ y-intercept for the function over the intervals x≤−1 and x>−1​?

The​ y-intercept is included in the piece of the function that crosses the​ ​ (a)   The piece for the interval ​ (b)  

• y-axis

• x-axis

• x>-1

• x≤-1
